Intravascular ultrasound (IVUS) has been used extensively in coronary applications. Its use in venous applications has increased as endovascular therapy has increasingly become the mainstay therapy for central venous diseases. IVUS has been used for both diagnostic and therapeutic purposes in managing venous stenotic disease, venous occlusive disease, and IVC filter placement and removal. IVUS has been proven to be effective in providing detailed measurement of the venous anatomy, which aid in determining the appropriate size and the approach for venous stent placement. In IVC filter placement, IVUS can provide detailed measurement and guide IVC filter placement in emergent and critical care settings. It also has certain utility in filter removal. At any rate, to date there are only a few studies examining its impact on patient outcomes. Prospective randomized controlled trials are warranted in the future.
血管内超声（IVUS）已广泛应用于冠状动脉领域。随着血管内治疗成为中心静脉疾病的主要治疗方法，其在静脉疾病中的应用也有所增加。IVUS 已被用于诊断和治疗静脉狭窄性疾病、静脉闭塞性疾病以及 IVC 滤器的放置和取出。IVUS 已被证明在提供静脉解剖结构的详细测量方面非常有效，这有助于确定静脉支架放置的合适尺寸和方法。在 IVC 滤器放置中，IVUS 可以提供详细的测量并指导紧急和重症监护环境中的 IVC 滤器放置。它在滤器取出方面也具有一定的作用。无论如何，迄今为止，只有少数研究检查了它对患者结局的影响。未来需要进行前瞻性随机对照试验。
